4). After baseplate is anchored and leveled with specified space between it and
foundation, it must be grouted in a manner as described under GROUTING.
3.2.3 BASEPLATES (OR SOLEPLATES) IN TRAIN.
Where driver, pump, and any other unit that couples in train with the pump will be mounted on
separate baseplates (or soleplates), you must align their common centerlines (see BASEPLATES
AND SOLEPLATES IN TRAIN and MULTIPLE BASEPLATES IN TRAIN figures) before
grouting them. You must also precisely level them. Failure to either properly align or level the
baseplates (or soleplates) will make shaft alignment difficult, if not impossible, without breaking up
the grout; a laborious and time consuming task.
You should begin work by aligning the centerline of the baseplate (or soleplates) of the principal unit,
usually the turbine or the high-speed pump, with your plant's bench marks, thereby establishing a
common centerline with which the centerlines of the other baseplates (or soleplates) that are in train
may be aligned (see BASEPLATES AND SOLEPLATES IN TRAIN and MULTIPLE
BASEPLATES IN TRAIN figures). Proceed with your aligning and leveling work as follows:
1. Verify that your foundations as described under PREINSTALLATION, section 1, have had
ample curing time; otherwise they may not support weight of baseplates (or soleplates) and
operating units.
2. To assure sufficient grouting, provide for a minimum space of one inch (25 mm) between
baseplates (or soleplates) and their foundations by placing shims adjacent to each foundation
bolt hole or beneath each leveling screw.
3. Set all baseplates (or soleplates) on shims or leveling screws, bending anchor bolts as
necessary to align them with holes in baseplates (or soleplates).
NOTE
Pump feet and their holddown bolts are inaccessible with
lagging in place.
4. If pump is on a baseplate (all other units must be removed from the baseplate) remove
lagging, if installed, from top of pump; also, to eliminate any torsional affect that the pump
might exert on baseplate, loosen holddown bolts at each pump foot (see LEVELING PUMP
END CROSSWISE figure).
5. Thoroughly clean surfaces of all mounting pads including exposed edges of pads at each
pump foot.
NOTE
If foundation bolts prevent precise alignment, relocate them
to assure that the centerline of every baseplate (or pair of
soleplates) will match the common centerline; also, before
making a final check of the centerlines for exact match, the
baseplate (or soleplates) should be almost level.
